Application led May 5, 1911. Serial No. 625,320.

To ad l1i/wm t may concern.'

Be it known that I, PATRICK Dflxlonnax, a citizen ot the United States, residing in the borough of Manhattan. in the city, ..ounty, and State of New York, have invented certain new and uset'ul lmprovements in Snow-Destroyers, of which the following is a specification, reference being had to the accompanying drawings.

'lhisinvention relates to improvements in snow-destroyers; and an object of this invention to provide a snow-destroyer which will he practical, which will he complete in all its parts and by which the ice and snow may he removed mechanically and directly from the highway, reduced lto a Atluent state and discharged into a drain or sewer.

Another object of this invention is to provide a snow-destroyer with snow-plowv mechanism.

A third object of this invention is to provide a snow-destroyer with mechanism so arranged that it may he used at will either as a snow-plow or as an intake mechanism.

A fourth object of this invention is to provide a snow-destroyer with street-sweeping mechanism by which the snow may be swept from the streets, reduced to a fluent state and discharged from the machine into a sewer or drain.

fifth objectl of this invention to provide a wmv-destroyer with means -t'or re moving ice from the roadway and onvcy ing it to the snow-destroying mechanism.

A sixth object of this invention is to provide a ,snow-destroyer with etlicient triturating devices by which the `snow and ice will be reduced to a fluent state.

An eighth objecty of this invention is to provide a snow-destroyer with etiicientand convenient discharge mechanism.

ninth object Qi this invention is to provide a mmv-destroyer with a sluiceway for receiving the ucnt mass from the discharge conduit and leading theI same to a sewer or drain.

tent-h object ci this invention is to provide a snowdestroyerwith mechanism for hauling a sluiceway. hosepipe and the like from one point in the street to another.

Other features or" this invention will be hereinafter referred to in the description and claims.

Generally described my new snow-destroyer comprises in combination intake mechanism, conveying mechanism, snow-destroying mechanism and discharge mechanism. The vehicle upon which the parts of these mechanisms are carried is preferably self-propelled; and as the vehicle advances along the street, the intake mechanism removes t-he snow and ice therefrom and directs the same to the conveying mechanisn'i by which it is lled to the snow-destroying mechanism. By the latter mechanism the snow and ice are reduced to a fluent state in the machine. The fluent mass is then discharged into a sluiceway and led to the sewer or drain.

ln the preferred embodiment of my invention hereinafter described the snow-de- 4,stroying mechanism is of the trit-urator type. Water is led to the triturator from the pressure mains of the citys water system and is caused to fall in the triturator upon the snow and ice in the form of a shower, which is nature`s most effective means of melting snow. To aid in the reduction ofthe, mass of snow and ice to a iuent condition, it is ground in the presence of water, or triturated. Suitable means are provided for cleaning the roadway thoroughly of the snow and ice in a highly efficient manner.

In the drawings illustrating the principle of this invention and the best mode now known to me of applying that principle, Figure l is a plan; Fig. 2 is a section on the line .\-A. of Fig. l; Fig. 3 is a bottom plan view; Fig. 4 is an end View; Fig. 5 is a detail yon an enlarged scale of the intake mechanism; Figs. 6 to 9, inclusive, are details illustrative of the ice-cutting and breaking mechanism; Figs. 10, l1 and 1Q are details showing the street-sweeping mechanism and its conveyer; Fig. 13 is a side elevation and Fig. 14 is an end elevation of the sluiceway; Figs. 15, 16 and 17 are details of the construction of the sluiceway; Figs. 18 to 24. inclusive, are details of the triturating mechanism; Fig. 25 shows in plan an agitator; Fig. 26 is a det-ail in plan of the front part of the intake mechanism; Fig. 27 isa detail showing an intake mechanism provided with a rotary broom; Figs. 28, Q9 and 30 show details of the construction of the conveyer leading from the intake; Fig. 31 is a detail showing the construction at a joint in the discharge conduit: Fig". 32 is a det-ail showing a device for the conveyer plates; and 33 is a detail in section showing the inode of fastening the plate-holding brackets to the ccnveyer-chains so as to allow play of the brackets.

llhe working parts of the snow destroyer' are carried by a vehicle a which is pre-ferably of the self-propelled type. The vehicle frame or chassis b is preferably of metal, such as structural or angle steel. ln this vehicle frame is supported in any suitable manner an engine or motor c, which may be of any suitable type, such as an internal combustion or gas engine. The vehicle frame 7J is supported upon the rear wheels d and 'the front wheels e; and to propel the vehicle, the following arrangement of parts is provided: lin shaft hangers f the upper ends of which are fastened to the vehicle frame in any suitable manner there is mounted a lengthwise-extending shaft g on which is mounted fast a sprocket wheel z connected by a chain 'L' with the sprocket wheel j fast upon the engine shaft 1'. On the front end of the shaft g there is mountcd fast a vbevel gear ym which meshes with a bevel gear n; and upon the rear end of the shaft g there is mounted a bevel gear o whih is keyed to the shaft g vand is, there-v fore7 lengthwise movable thereon. Near the middle of the vehicle there is mounted or journaled in the lower end of the shaft hangers g a transverse shaft p,- and on the latter there is loosely mounted a sprocket,

wheel s, while the bevel gear n just referred to is fast on the shaft p. The sprocket wheel .v isconnected by the sprocket chain t with the sprocket wheel u which is fast upon the rear axle 'u and which drives the rear wheels rf to propel the vehicle. integral with the bevel gear n, is a sleeve n upon which is keyed a slidable clutch n adapted to be thrown by a system of levers s into and out. of engagement with the sprocket wheel s to start and stop the propulsion of the machine. By reversing the engine c the ve hicle may be moved to the rear. Near the drivers seat s there is carried a steeringshaft r on the upper end of which is mounted fast a steering-wheel r and on the lower end ofxwhich is carried a transverse bar r" the ends of which are connected by links c with the swinging axle-ends e on which are mounted in the usual manner the front wheels e of the vehicle.

At the front end of the machine there is carried a bell-mouthed or trumpet-shaped intake w; and extending transversely there` of is a rotary shaft y which is journaled in the journallboxes a: mounted slidably in the slots or openings e in the side walls of the intake. lFastened to the sides of the intake fw is a pair of brackets 2 through which extend the threaded upper ends of the screwstuds 3 the lower ends of which are attached insaeee to the journal-boxes a3. llpon thc threaded upper end of each of the screw-studs 3 there is mounted an adjusting nut 5 which bears upon the bracket 2 and by turning which the shaft y may be raised and lowered. lly means of the lock-nut 4l 'the screw-'studs 3 may be held in their adjusted positions. Fastened upon the transverse shaft y by a spline or feather 6 is a series of ice-cutting circular saws 7 between each pair of which is mounted a rotary ice-breaker 8. The hub 9 of each of these ice-breakers S is secured to the transverse shaft y by the spline or 'feather 6 and from each of the hubs 9 extend radially the ice-breaking blades 10 which are of less length than the radius of the saws 7, whereby the latter are permitted to sink into the ice to cut the same. By means of the adjusting nuts 5 the shaft y/ may be raised and lowered so as to adjust the saws 7 and blades 1() for different thicknesses of ice upon the roadway. lWhen there is no ice on the pavement, the ice-cutting and breaking mechanism just now described may he replaced by a rotary brush or broom 7 shown in Fig. 27. The intake 'zc communicates with the lower end of the belt-conveyer casing 11 to the bottom wall of which at. the lower end thereof is pivotally mounted the rear end of a lshovel 12. As the vehicle movesl forward, the shovel 12 directs the -snow and ice into the conveyer casing 11.

1n the top of the latter there is mounted a rotary shaft 13 and in its bottom is mounted another rotary shaft 14; and over sprocket-wheels 13-` 14', on these rotary shafts 13, 14 respectively pass endless chain belts 15 to which are fastened the conveyer plates 16. At the top and bottom. respec tively, of the conveyer casing 11, there are mounted the rotary shafts 17, 18 over which and the rollers 19 passes the endless supporting belt 19, by which the weight of the incoming snow and ice is supported.

The chain belts 15 are driven in the following manner: Upon one end of the transverse shaft p there is loosely mounted a sprocket wheel 2O which is connected by the sprocket chain 21 with the sprocket wheel 22 mounted fast. upon the upper rotary shaft 13. Keyed upon the shaft p is a slid able clutch 23 which may, by means of the clutch lever 24. be thrown into and out of engagement with the sprocket wheel 20 to clutch the latter to the transverse shaft p, which is driven by the bevel gear n fast thereto. The lower rotary shaft Mis driven by the chain-belts 15 from the shaft 13. Upon the latter there is mounted fast a spur gear 28 which meshes with a spur gear 29 fast upon the rotary shaft 17 `whereby this rotary shaft 17 is driven from the shaft 13. Upon one end of the lower rotary shaft 14 there is mounted fast a sprocket wheel 30 connected by the sprocket chain 31 with a sprocket wheel 32 fast upon one end of the transverse rotary shaft y which drives the ice-breaking and cutting mechanism hereinbefore described or the rotary broom 7 when. the same is substituted for the latter mechanism. The conveyer plates 16 are fastened to the chain-belts 15 in the following way: To the latter are fastened plateholding brackets 33 formed with slots 34 into Which are slipped the plates 16. These plates at their inner edges are formed with a tube 16 and with notches 16X; and a locking pin 16 is slipped through this tube 16 and through the holes in the bases of the brackets 33 to hold the plate 16 in place.`

This arrangement of parts enables the conveyer plates 16 to be fastened' to and removed most readily from .the endless chainbelts 15 in case of need. The bottom faces of the plate-holding brackets 33 are curved and recessed to permit the same to conform to the curvature of the sprocket-wheels 13', 14 and to pass readily thereover. To add to the rigidity of the structure, the lower end of the conveyer casing 11 is supported upon rollers or small wheels 11.

To enable the vehicle to plow its way through the snow the chassis b of the vehicle is made V-shaped at its front end, as is shown at b and to each side of the intake 'uf is hinged a door 1.1:" having a rearwardlyextendingr wing wx. One of the doors w is provided at its front edge with hinged clasps having .at their free ends winged screw-bolts 26 b v which the clasps may be fastened to the other door to lock the doors together in closed position to form a snowplow. Each side o of the V-shaped front part of the chassis is formed with lugs b having holes o* through one of which and a hole in thc top part of the wing z/'X in register therewith may be passed a pin 2T. To insure that the wing yuf and the door vw of which it forms a part shall be held firmly in adjusted position, each side of the intake w is provided with an outwardly-extending perforated arm 25 and each wing yw is provided with an in\\'ard1ye.;tending perforated arm 25" arranged to lie close to the arm 25'. A pin 2T may be dropped through any pair of holes in the arms 25. 25 which are in register with each other to lock the arms together. iVhen it is desired to use the doors fw to guide the snow into the intake, they are thrown outwardly from each other as is shown in Fig. 26, and each door is held in this position by an l -shaped locking-bar 26 the vertical leg of which is mounted in clips 26 fastened to the outside of the door 11" horizontalarm of which hooks into one of the holes 2T in the V-shaped part Y1 o f the chassis Z1. wWhen the doors are closed, the vwings yzox are thrown outwardly and serve to ont a suciently wide path through the and the. free end of the shown by the dotted lines in Fig. 26 and the full lines in Fig. 3. The bottom edge of each door w is provided with rollers 27 bv which the' door is in part supported.

Each `side of the intake w is formed with av curved slot l2 through which projects outwardly a threaded stud 12" from the adjacent side of the shovel 12. the handled nuts 1:2x on the outer ends of the studs 12 the shovel 12 may be heldin adjusted position.

To insure that the pavement Will be thoroughly cleaned of the snow, I have provided in the rear of the conveyer casing 11 a street-sweeping mechanism which may be described as follows: Journaled in the ends of a suitable casing or housing 36 is a rotary shaft 37 upon which is mounted within the casing 36 a-drum 38. carries brush material 39 of any suitable character which is held in a .groove-in helical ribs 38 upon the drum 38. The shaft 3T is preferably inclined to the longitudinal axis of the vehicle and the sweepings are. collected at one end of the br-ush casing 36 from which extends upwardly and rearwardly a `screw-conveyer casing 40 within which is mounted a screw-conveyor 41. To drive the shaft 37 there is mounted upon one end thereof a bevel gear 42 which meshes with a bevel gear 43 on one end of the lengthwise-extending shaft 44 on the other end of which is a bevel gear 45 in mesh with a bevel gear 46 loose upon the transverse shaft y). Adjacent to the bevel gear 4.6 there is keyed upon the transverse shaft y? a slidable clutch 4T which is controlled by the clutch-lever 43. By manipulating the latterthe bevel gear 46 may be clutched to and unclutched from the transverse shaft j) to throw the sweeper or brush 38 into and out of operation. Upon the end of the shaft 3T opposite from that upon which is mounted the bevel gear 42 there is mounted another bevel gear 49 in mesh with a bevel gear 50 mounted fast upon one end ot' the shaft 51 upon the other end of which is mounted fast a sprocket wheel 5:2 connected By tightening The latter.

bv a sprocket chain 53 with the sprocket. y

wheel 54. The latter is mounted fast upon the projecting lower end ofthe 'screw-conveyer shaft The brush or sweeper 39 will throw the sweepings from the street pavement into the screw-con.'eyer casing-10 at the lower end thereof whence they will be carried up by the screw-conveyer ti. 'ifo the lower end of the screw-conveyer casing 40 there is pivotally fastened a dan or plate 56 to the lower end of which is secured one end of an adjusting chain 5T the other end of which is detachably fastened to a support 58. The iap or plate 5G may be adjusted the chain and will prevent the sweepings from being thrown outwardly to the front and beyond the flap by the sweeper 39.`

Mounted free to swing near the rear lower edge of the housing 36 opposite the flap 56 is a transversely-disposed trailer-broom 56 having a hole in each end into which and through one of the holes 57 formed in the lng 57 may be thrust a pin-bolt 56 to hold the trailer-broom 56 at its adjusted height. The trailer-broom insures that the roadway shall be swept clean. Supported by the chassis l) is a transverse beam 36 through Y which distributes water in front of the rotary broom 39.

tlentrally disposed within the triturator shell 59 is an upright or vertical shaft 60 upon the upper end of which is mounted fast a water-wheel or water-motor 61 of any suitable type and upon the lower end of which is mounted a bevel gear 62. 'Water is led from the water-pressure mains (not shown) to the hydrant 136 and thence through the hose-pipe 125 to the water pipe 63 from which it flows in jets through the nozzles 64 and is directed by the latter against the buckets or vanes 65 of the waterwheel 61 to drive the lat-ter. lf it be desired to have the assistance of the engine c in driving the vertical shaft 60, the bevel gear o is thrown into mesh with the bevel ucar 62 by means of the clutch-lever 66 the workingr end of which is engaged with the grooved hub 0 of the bevel gear o. The latter is mounted slidably upon the shaft f] by being keyed thereon.

The triturator shell 59 is braced by means of a spider 67 the outer ends of the arms of which are suitably fastened to the shell l59 and through the hub of which passes free to rotate the central vertical shaft 60. Mounted upon the latter above the spider 67 is a distributer the arms 68 of which are inclined to the vertical andwhich carry downwardly-projecting teeth or prongs69. By reason of their inclination to the vertical. the distributer arms 68 will allow the mass of snow, ice and water to fall freely through between them and will tend to force downwardly the snow and ice, distributing the same between the arms of the spider 67 and the teeth or prongs 69 will break up any lumps in the mixture. About midway of the trturator-shell 59 there is mounted a aparece gratin 76 having upwardly-projecting teeth (1; and. between the grating 70 and the spider 67 there is mounted fast upon the central vertical shaft 60 a cutter 72 the blades 73 of which are inclined downwardly and are formed with serrated cutting edges 74, the teeth of which co-act with the teeth 71 to grind and pulverize any hard substance, such as small stones or pieces of ice, that may have accumulated upon the grating 70. rlhe upper edges of the blades 73 sweep pastl the arms of the spider 67 and cut away the downwardly moving parts of ice and snow falling between the arms. lt is to be observed that there are an inner series of blades and an outer series of blades 73 with openings 73 between the blades of each series. The outer series contains about twice as many blades as the inner series. In the lower part of the triturator shell 59 there is mounted an inner shell or annular wall 75 the upper end of which is connected to the shell 59 by the frusto conical ring or section 76. 'lhe lower part of the latter is braced by a spider 76 and t-he inner shell 7 5 is bracedby means of a series of spiders 77. lWithin thc inner shell 75 and near the top thereof there is mounted fast upon the central vert-ical shaft 60 a sweep 78 the blades 79 of which are inclined to the vertical and will cut away the triturated ma terial falling between the arms of the spider 76 and projecting downwardly therethrough into the path of the blades. The latter will also press downwardly the mass below them.

Mounted tast upon the vertical shaft 60, onebetween each pair of spiders 77, is a series ot agitat-ors the blades 80 of which agitate and break up the mass within the inner shell 75.- The screw conveyertl discharges the swcepings into the space be* tween the inner shell 75 and the lower portion of the triturator shell 59 and just be lpw the frusto-conical shell 76. Near the bottom of the triturator shell 59 there are fastened to the central shaft 60 agitator frames 8l the sides of which carry upright agitator-posts 82 which stir up the Huid mass within the space just referred to.

This fluid mass overflows through the discharge opening 83 into the discharge conduit 84 and its outward movement is assisted by the centrifugal action of the agitator posts 82. The conduit 84C is formed with a manhole closed by a manhole-cover 85 by removing which access may be obtained to the interior of the conduit. rlthe belt conveyer 15 discharges into the triturator near the top thereof the mass of snow. and finely broken ice particles scooped up by the shovel 12. A stationary scraper 19 fastened to the shell '59 cleans od the belt 19 thoroughly. lUpon its discharge from the belt conveye115, this mass is thoroughly saturated with water flowing under high pressure from a spout 86 which is connected with the inlet-water pipe 63. A valve-controlled branch-pipe 87 leads water from the water-pipe 63 to the shower-producery 88. (In this way there is artificially reproduced in principle natures most et'- fective methodV of melting snow, a rain storni.) The water pours down upon the snowy mass beneath and aids thereby in reducing the saine to a condition in which it is readilyv triturated by the triturating devices below the shower-producer 88 and hereinbefore fully described. Moreover, the supply ot' water under pressure thus provided produces a rapid flow of the contents ot' the triturator shell outwardly through the opening 83 and conduit 84 and thence into the sectional discharge-pipe 89 from which it is discharged into the sluiceway 90 and troni the latter into the drain 91 from which it flows into the city sewer.

Hingedly mounted in a bracket lug 92 fastened to the rear of the triturator shell 59 is an arin 98 which carries at one end a. ring 94 having a series of holes 94. At the center oi' the ring 94 there is pivoted one end ot' a bar 95 to the other end of which is fastened by a -suitable clamp 96 a bar 97; and to the latter is clamped a third bar 98 to the outer end of which is fastened one end ot' a guy rope or cable 99 which passes over a roller 99 and the other end of which is wound on a drum 99 controlled by a pawl 99", the drum and the roller being supported by the shell 59. rThe clamps 96 are slidable with-respect to the bars upon which they are mounted and trono this it follows that the'bars 95. 97 and 98 may be adjusted relatively to each other to lessen or to increase thetotal length of the support made up of these bars. F rom the latter are suspended or slung by nieans of the sling chains 100 theseeions ot the discharge pipe 89. These sections are arranged to telescope into each other, so that the total length of the discharge pipe 89 may be increased or diminished as may be found necessary. The joint between any two sections is watertight.; and this watertight construction is illustrated in Fig. 81. The ends of both the inner and outer sections at the joint are formed with flanges 89, 89 which extend in opposite directions and between which is mounted a rubber packing ring or gasket ring 101. The end of the outer section is slitted to make it yield readily and over this slitted end is fitteda split hoop or band 102 the ends of which may be pressed together b v any suitable device. as by tightening the bolt 102'. The bar 95 is formed with a hole adapted to be swung into register with any one of the series of holes 94 in the ring 94; and when the bar 95 is properly positioned, it is held in place by a lock-pin 95 vwhich passes through the hole 95 and the hole 94 in register therewith. From this arrangement of parts it follows that the system of bars 95, 97, 98 may be swung in a horizontal plane from side to side of the machine. Further, the inlet end of the discharge pipe 89 is pivot-ally mounted upon the outlet end of the conduit 84 so that therdischarge pipe 89 may be swung in a vertical plane from side to side of the machine, the sling chains having first been removed. The outlet end of the discharge pipe 89 is provided with a canvas pipe 103 to which is fastened a chain 104 one end of which is attached to a ring at the outlet of the conduit and the other end of which is provided with a split ring 104 slidably engaged with a guide wire 105 which extends lengthwise of the sluiceway 90. The latter is sectional in construction and the joint between abutting sections or gutters is made watertight byv means of a strip of rubber or other suitable packing l106 fitted in grooves in the opposed ends of the sections. To lock the abutting sections securely together, .one of the opposed ends is provided with a loop 107 and the other end with a pivoted clasp 108 adapted to pass through the loop 107 and then to be thrown against the wall of the gutter to lock these ends together after the manner of a trunk fastener. The gutter sections are supported on legs 109 provided at their lower ends with rollers 110 and pivoted at their upper ends to the sides ot the gutter sections. These sides are provided with y graduated semicircular segments 111 each formed with a slot 112 through which and a hole in the leg 109 passes a bolt 113 upon the threaded outer end ol which is screwed a wing nut 114. By loosening the latter the legs 109 may bc adjusted so as to give the gutter any suitable inclination desired. Rach end section 90' of the sluiceway 90 has its lateral walls at one end raised above the general level ot the section and the end section next the drain 91 may be provided `with a Suitable grating 115 which is designed to prevent rubbish and debris floating in the stream Vin the sluiceway from falling into the drain. To permit this end section 'to be cleaned. it is provided with a slidable gate 116, which may be raised vertically to allow the sediment collected in the bottom of the section to be cleaned out.

Mounted loosely on and, therefore,f1ee to rotate independently of, the axle' v is a. drum 117 upon which isl rovea rope 118 carrying at its outer free end a swivel-hook 119. Fast. to the drum 117 is a sprocket wheel 120 which is connectednby the sprocket chain 121 to a sprocket wheel 122 loosely mounted' upon the transverse shaft y).

Keyed upon the latter isa clutch 123 which may be thrown into and out of clutching engagement with the sprocket wheel 122 by means of the clutch lever 124. When the machine has proceeded along the city street to the next hydrant, the hydrant end of the hose-pipe 125 is uncoupled from the hydrant and made fast to the hook 119 of t-he windlass rope 118. Upon the bottom face of each side member of the chassis Z) is pivotally mounted a pair of pulleys 126; and the rope 118 is passed between one pair ot' these pulleys. By means of the clutch-lever 124 the clutch 123 is thrown into clutching engagement with the sprocket wheel 122 and thereby the windlass is rotated to wind up the rope 119 and pull the hydrant end of the hose-pipe 125 up to the next hydrant. When the hose-pipe is not in use, it will be Wound upon the hose reel or spool 127. Each of the end sections of the sluiceway is provided upon its bottom with an eye 128 with which may be engaged the swivel hook 119, the rope 118 being passed or rove through pulley or sheave of a block 129 hooked or otherwise suitably fastened to the wall of the drain 91. By winding the rope 118 upon the drum 117, the sluiceway 90 may be moved from one drain to the next.' A suitable truck 130 may be attached to the rear of the vehicle a for t-he transportation of the sections of the sluiceway, when the same is not in use. One of the end sections of the sluiceway is provided with a reel 131 upon which may be wound the part of the guide-wire 105 not in use. The reel is prevented from unwinding by a pawland-ratchet mechanism 132.

A conduit 133 leads from the bottom of the triturator shell 59 to the conduit 84 and is controlled by a valve 134, by opening which' the trituratorshell may be drained of its liquid contents. IThe hydrant-end of the hose-pipe 125 is provided with a valve 135 by which the water in the hose-pipe may.

be retained therein, after it has been uncoupled from the hydrant 136. ln this way the street is kept free from water ,which might otherwise overflow it from the hosepipe.,A The discharge pipe 89 is provided with a valve 141 which is thrown into closing position, when the operation of the machine is stopped.

To clean from the 'lates 16 any material .which may cling to t em, a cleaning-bar or Wiper 137 is mounted free to rock in the side-Walls of the conveyer-casing 11 and is -controlled by the torsional springs 138 Vas mounted on its ends and thereto attached, the springs being also attached at one end to the adjacent wall of the casing 11. A strip-pin 139 limits the downward movement of theaiper 137. As each plate 16 moves around the upper shaft 13, its working face is wiped by t e yieldingly-mounted wiper Loanaea and the caking of snow between and on the plates is prevented.

The exhaust gases from the gas engine r: are led to the interior of the triturator shell 59 through an exhaust-pipe 140.

.lVhen the doors w are open, as shown in Fig. 26, a wire-mesh grating 141 is fastened to and between them in order to exclude debris which might otherwise reach the conveyer and therethrough the interior of the machine. The shell 59 of the triturator is formed near its bottom with a manhole normally kept closed by a suitable cover 59X. By removing the latter access may be obtained to the interior of the shell for the purpose of cleaning.

To insure the easy passage of the brackets 33 over the sprocket-wheels 13, 14, and reduce the shock which accompanies the change in direction and thereby to prevent breakageof the arts, the brackets 33 are so connected to t e chains 15 that there is play between the connecting and connected parts. Thus, the holes 33 1n the brackets 33 are made larger than the rivets 33 which fasten these brackets to the con veyer-chains 15, whereby some play is al lowed the brackets. 1n this way the strain at the turn is brought upon the chain and not upon the brackets and some resiliency is given to the conveyer-plates 16.
